METAL MOLDING.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed November 24, 1908. Serial No. 464,294.

To all whom it may concern:

Be it known that 1, PAUL T. IQENNY, a citizen of the United States, residing in the borough of Manhattan, in the city, county,

and State of New York, have invented certain new and useful Improvements in Metal.

Mol din (I of which the following is a speci molding adapted to carry electri c'wires or to support pictures or both, to enable the molding to be put up after its sustaining screws or equivalent supporting devices have been sunk into the wall or ceiling, to insure the retention of the 'wires in the molding while the latter is being erected, to enable the molding to be supported clear of the wall or other supporting base, to present improved two-part moldin construction, and to minimize the cost an labor of installation. v

The invention may be said toconsistin the various features ,of construction and combinations of parts by which these ends are attained; and in the specification and the accompanying drawings will be described and illustrated some of the possible embodiments of the invention, while the appended claims will set forth the essence of the invention in its various phases.

In the drawings, Figure l is a bottom plan of-a form of molding embodying my invention;Fig. 2- is a cross section on the line 22, Fig. 1; Fig.3'is across section on the line 33, Fig. 1, showing a picture hook in dotted lines; Fig. 4 is a cross section of a three-wire construction, instead of' a twowire construction asin the preceding views;

' Fig. 5 is a similar view of a four-wire construction; and 6 and 7 are two perspective views of orms of molding embodymg the invention and provided with alternative forms of capping devices.

Metal moldings constructed after my invention may comprise such'a trough or body as designated by the numeral 1 in the several views, which is provided interiorly with any desired number of grooves or channels 7 used for electrical purposes. Figs. 1, 2, 3, 6- and 7 show two-wire constructions; and Figs. 4 and 5 show three and four wire constructions, respectively. This trough or body 1 may be provided with a separate capping member or plate such as that designated by the numeral 5 in Figs. 1 to 5. Ac-

"terva cording to this particular construction, the capping 5 clasps at its longitudinal edges over the upper and outer edges of the troughshaped bodv 1; and it is preferred that the metal of the molding be sufficiently resilient to allow the cap to be sprung on and off the body. ()1' other two-piece constructions may be employed, such, for example, as illustrated in Figs. 6 and 7, where a capping plate 5 slides in the vupper edges of the troughshaped body 1.

One of the primary features of novelty of the underside of the body of the molding, which are adapted to be received over the heads of screws 4 or equivalent devices, after the latter have been inserted in the wall, ceiling or other base. vThesesockets are advantageously provided in the form of the external grooves 2, alternating with the interation' o the metal plate from which the ody 1 was formed. This socket or groove '2 represents on the underside of the bodyl the ridge which separates the grooves. This ridge is wider above and below, wherebythe invention is the provision of sockets in Y mil wire grooves? as the result of the corruthere is a two-fold result: First, the grooves 7 are constructed to hold the wires irrespective of capping; and, second, the groove 2 is constricted to receive and hold the heads of the fastening devices 4. Preferably the.

bottoms of the grooves 7 are rounded, 'so

thatthe mouth of the groove 2 flares some reduced, this for thereasons that it lS IHIIClI easier to insert the fastening devices 4 in the supporting base without holding the mold ing in place during the operation, and that the wires do not have to be held inthe molding by a helper during the erecting operation, since they are seeurelyheld in place by the cappin 5 or 5*, which does not have to be removed during installation. Further, all screw holes in the molding are avoided,

thus guarding againstthe admission of moisof my socketconstructiom labor and expense of installation are greatly tiire; IMoreovr, as indicated in the views,

further to guard against entrance of IllOlS- ture, the molding maybe held away from the surface of the wall-or other supporting base, byreason of the length of the exposed portion of the supporting devices t, Another salient feature of novelty is the construction I of ,thewire-receiving grooves 7, so that, irre-' spective of the capp1ng5 or 5, the wires will be held iii-position during the erection of the molding. This is accomplished, as

tendency of the wires to fallout of the body o, .nofcthellLqld g l V g Of course, t Ts-tobe understood that the molding, 'viewed as: an electrical molding,

may be enameled, asis customary, or treated in any other w'ay'to make it conformable to the requirements of theunderwriters. v 7 What I claimas new is:

l. A metal molding adapted to carry electric wires or to seiive as a picture molding, consisting fgaa gu' h-sh g d b d a d' 'ailj cover thereto"1",?said ody being bent from,"

sheet metal topresent interiorlya plurality of grooves for the reception or electric wires, and a ridge separating said grooves,

2. A metal molding adapted toc'ari'yeleo.
